The Rice Lake ASTM Class 3 Calibration Weight Set is engineered for professionals who require dependable reference standards for frequent verification and calibration tasks. These polished stainless steel weights deliver the necessary accuracy for routine checks of analytical and precision balances, tolerance testing, and student laboratory use, where robust performance is prioritized alongside value. The set’s compliance with ASTM E617-23 ensures it meets recognized industry standards for its class.

Applications for this set are broad, serving as a practical tool for rough weighing operations, initial balance calibration, and the verification of lower-class working weights. The weights are marked with their nominal value and, consistent with ASTM E617-23 for this class, are not individually serialized; traceability is provided through a serial number applied to the storage case. This design offers a streamlined solution for environments where individual weight certification is not mandated but reliable conformance to a published standard is essential. The set is housed in a protective case, with larger sets featuring a durable hardwood and velvet-lined presentation.
